500W MMDS Indoor Digital Transmitter
Outline
Thanks for choosing our products.
TY-2650A 500W MMDS Indoor Digital Transmitter is a kind of digital facility working on S band (2.0-2.9GHz). This equipment adapted latest generation power amplifier chip LDMOS. It supports both analog and digital modulation and adapts to multiple modulation modes like DVB-S/S2, DVB-T/T2,nQAM, ISDB-T/TB and etc. AGC/ALC function guaranteed the reliable operation of the equipment by maintain constant power output of transmitter. Its LCD display shows the parameters of output power, working voltage and AGC, can monitor the abnormal values real-time. It also has auto-alarming and lightning-proof functions. As the advantages mentioned above, this equipment can widely apply to point to point and point to multi-point transmission and signal coverage.
Main features:
With touchable LCD control panel to adjust the key parameters: Ouput power range,Input level range,AGC range and monitor the abnormal values real-time.
Adapted new generation power amplifier (transmitting power increased and un-linear distortion effectively decreased).
Aluminum structural design, with natural heat dissipation or forced air cooling design, equipment operational reliability can be improved.
Signal debugging design (maintenance can be simply carried out).
Simple debugging procedure, signal opening can be achieved without specialized instruments.
Multiple choices in power level and local frequency.
Extended interface for remote control.
Small in size, easy for construction and maintenance.
